THE SIGNAL BOX

OVERSEAS

DENMARK

Mechanical signalling in Denmark followed the practice of many other European countries by utilising double-wire frames and German-style signals with the well-known "blob" at the end of the arm. But the principles of German signalling were not adopted and many features of their system bear closer comparison with British practice. Distant arms had a type of fish-tailed end, and signals at junctions defined which route the train was to take in preference to a speed signalling system.

This system has followed a natural development into the colour-light signalling of today, which features diagonal indications to indicate junction routes. The system has been enhanced to cope with the demands of modern signalling by illuminated boards mounted below the signal aspects which define, by means of a range of white lines, the permitted speed over the junction ahead.
